COMBINED ROLLER AND CULTIVATOR.

SPECIFICATION' forming partof Letters Patent No. 352,923, dated November 23, 1886.

Application filed May 5, 1886. Serial Nic. 201,174. (No model.)

To all whom, it may concern,.-

Be it known that I, JAMES MILLS, of Keyesport, in the county of Clinton and State of llli nois, have invented certain new and useful Improvements in Combined Rollers and Cultivators, of which the following is a specification.

In my improved machine the cultivators precede the rollers andare mounted on a shaft driven from the roller-shaft. The cultivators are vertically adjustable, so as to vary the depth of cut or to withdraw entirely from the soil. The driving-gear between the cultivatorshaft and the roller-shaft is arranged to turn the cultivator-shaft only when the machine is advanced, and is readily disconnected, so that the machine may be used simply as aland-roller.

I preferably employ two rollers, one being fast on the shaft and the other loose, the two rollers being connected by devices that permit the rollers to travel 'together when the machine advances, but permit of an independent movement when the machine is backed or turned.

In the accompanying drawings, Figure 1 is a plan of my improved machine; Fig. 2, a side view; Figs. 3 and 4, detail views ofthe devicesfor connecting the rollers together.

rlhe rollers A Al are mounted on a common shaft, a, and are `journaled in bearings b in the main frame B. The roller A is fast on the shaft a. The roller A is loose on said shaft. On the inner end of the roller A, near its axis, is a Spring-pawl, b', that engages with a ratchet-wheel, b2, on the rollerv A. 'When the machine is advanced, the two rollers turn together. When the machine is backed or is turned, the pawl rides over the ratchet-wheel, thus disconnecting the two rollers and allowing them to have an independent and easier movement. When the machine is turned, the roller A moves in a contrary direction to. the roller A, thereby lessening friction and facilitating materially the movement.

The cultivators C are mounted on a shaft, c, journaled in bearings c in hangers 02.1'1 preferably employ cultivator -teeth such as illustrated, and arrange them in two rows on opposite sides of the shaft c. Each tooth is independently connected to the shaft by means of its shank c3 and a nut, c4, that fits on the screw-threaded end of the shank c3, that pro-k jects through the shaft.

n yOn the roller-Shaft a vis loosely mountedl a pulley, D, having on its inner edge an annular series of teeth, d, that normally engage with a toothed wheel, E, rigidly secured to the roller A. On the outer side of the pulley D is formed a drum, d', having an annular groove, d, in which lits the forked end of the shiftinglever F.

Between the drum d and the main frame B is interposed a spring, d3, that normally causes the teeth onl the pulley D to engage withthe toothed wheel E. :The shifting-lever F is pivoted to the rear of the main frame at f. The lever F has a right-angled extension, F', the

outer end ofwhich has a locking device, f, for

holding the lever when the pulley D is disengaged frm the toothed wheel E. The pulley Dis connected with a pulley, G, on the cultivator-shaft c by means of belt g, pulley g', shaft y, pulley g3, and belt g4. When the machine is advanced, (the shifting-lever-beng unlocked,)L the pulley D will engage with the roller A and the cultivator-shaft will be rotated. If the machine is backed, the pulley vD will slide on the Shaft t against the force of the spring, thus throwing the pulley out of gear, and the cultivator-shaft will not rotate.

A bridge, H, formed of two curved bars, h, extends over the rollers, and is secured to the front and rear beams ofthe main frame. Between the curved bars his bolted the tongue I. The barsA h preferably diverge from the top downwardly, so as, to effectively brace the bridge. A lever, J, is pivoted to the bridge, or to the tongue, as shown at j, and its outer end is4 connected to the front beam of the main frame by means of an arch-bar, j', through which the tongue extends. The upper end of the arch-bar is pivoted to the end of the lever J, as indicated at ji. The lever may be held in any desired position by means of the per- .forated curved bar K and pin k, or any other IOO the two rollers together when the machine i advanced.

2. The combination, substantially as set forth, ofthe main frame, the roller-shaft, the roller fast on the shaft, a second roller loose on the shaft, the ratcheiwheel on one of the rollers, and the pawl on the other roller, that engages with 'the ratchet-wheel when the machine is advanced, whereby both rollers are caused to turn together.

3. The combination, substantially as set forth, of the main frame, the roller or rollers, the cultivator-shaft, and gearing between the roller or rollers and the cultivator-shaft, that operates to revolve the cultivator-shaft when the machine is advanced, but thatfis inoperative when the machine is hacked.
